UNITED STATES METALLIC-ROOF JOINT.

PATENT. OFFICE.

Original application filed September 26, 1927, Serial No 222,006. Divided and this application filed April 19 1928. Serial No. 271,344.

My present invention relates to a joint for metallic members which is particularly adapted for locking together metal'sheets in the formation of a tin or metal roof.

The principal object of the invention is the provision of a joint of. the type described which will be water-tight, which will permit of the sheets being secured to the wooden roof sheathing without the securing means passing through the sheets themselves, and which provides a lock for the abutting parts.

Another important object of the invention is the provision of a construction which will permit ready separationof the parts should the same be necessary without mutilation of the metal strips so that they may be again used.

This application is a division of my copending application Serial Number 222,006 filed September 26,1927. I

To this end the invention contemplates a metal roof comprising elongated sheet elements having their extreme longitudinal edges formed into an upstanding wall having a return bent portion turned back towards the main body or sheet. This bend may be either sharp or arcuate. In use two of these longitudinally extending sheets will be placed adjacent to each other so that the upstanding wall along one longitudinal edge of each of 'two sheets will substantially abut each other, the return or bent portion of each wall extending in the opposite direction. I have found it desirable to provide a cleat or fastening element having an upstanding wall and a return bent port-ion adapted to partially overlie the bend in one of the longitudinal edge portions of the main roofing element, the remainder of the cleat adapted to lie flat upon thereof sheathing and to be nailed thereto Vith such a construction, a second elongated sheet member may then be placed in position with the main body of the clea-t underlying the same, the relation of the upstanding wall on the two adjacent sheet members existing as before. A

A cap having offset locks therein maynow be snapped over the two return bent portions of the sheet members, the offset locks engaging and opposing the raw edge of the return bent portions. This cap eflectively locks the two sheet elements together, and makes the joint between the two upstanding walls of waterproof nature.

The invention further consists in the novel arrangement, construction. and combination of parts hereinafter described, and shown in the accompanying drawings, in which Fig. 1 is a sectional view of a device embodying my invention.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is a perspective view of a complete sheet of metal constructed as in Fig. 1.

Fig. 4 is a detail of a cap element.

Fig. 5 is a detail of a portion of a cleat or fastening element.

Referring now with particularity to the drawings, I have shown a metallic element at A of elongated form, which consists of a main body 1 and a. marginal wall 2 upstanding therefrom. The top of the. wall is provided with a portion 3 bent or returned toward the main body. The opposite longitudinal edge of the sheet A is likewise'provided wit-h the same upstanding wall and return bent portion. The body 1 is adapted to lie upon the ordinary roof sheathing.

A second like metal element B having a body 9 and upstanding wall 10 is provided, the top of the wall 10 being returned bent as at 11, and in a similar manner to the longitudinal edge construction of the sheet A.

A cleat is provided consisting of a flat portion 5 with a wall 6, slit to form hook-shaped portions 7, the hooks overlying the bends formed by the upstanding wall and the re-.

turn bent portion of each of the elements A and B, the flat base 5 of the cleat being adapted to benailed to the roof sheathing as by nail 8. This effectively secures the sheets A and B to the roof.

Over the two return bent portions 3 and 11, I place a cap or saddle 12 provided with a series of offset locks 13. It is to be noted that themarginal edges of the cap 12 are sufficient in extent to project beyondthe marginal edge of the return bent portions 3 and 11, and that the lock 13 is located in this portion.

The lock itself consists simply of an offset part of the metal formed by slitting the cap as at 14 and deforming that part of the metal on one side of the slot to form an offset. It is to be noted that this offset portion must therefore of necessity be provided with a raw edge, and that this edge merges with the main body of the cap.-

Upon placing the cap 12 in position as shown in Fig. 1, the lock 13 will snap under the return bent portions 3 and 11, the raw IOU roof.

It is to be noted that this invention contem'plates a cap overlying a return bent portion of-an upstanding Wall of each of two abutting sheets, and that the cap and return bent portion are locked together by means of a resilient ofiset lock in one element, engaging a raw edge in the other element.

Having thus described my invention What I claim is: i

1. A roof joint comprising elongated inetallie sections, the adjacent longitudinal edge portion of each section having an upstanding Wall and a return bent portion, returned towards its respective body, acap overlying both return bent portions, a raw edge in the cap engaginga raw edge in each of the return bent portions.

2. A roof joint comprising elongated inetalli-c sections, the adjacent edge of each section having an upstanding Wall, each Wall having return bent portions returned towards its respective section, a cap overlying both return bent. portions, and extending beyond the same, and an offset lock in the projecting portion of the cap, and including raw edge engaging and opposing a rawedge in the return bent portion. 7

3. A roof joint comprising elongated nie tallic sections,- the adjacent edge of each sec tion having an upstanding wall, each Wall having return bent portions returned toward its respectivesection, a cap overlying both return bent portions and extending beyond the same, an offset lock in the extending portion entirely beyond the return bent portion, a raw edge of the lock engaging'the raw edge of the return bent portion. v

In testimony- Whereot', I ailix my signature.
